I guess I shouldn’t be surprised, but this topic veered off onto a pre-determined track not related to the topic.
I could dredge up the minutes and motions from the North American driver license design association which I have found online (not sure about the exact name, but it really exists and I have read them) and their efforts to bring all North American licenses into conformance with the Vienna Convention. But as you can see from the Alaska license above this group must exist, because the work is happening, licenses like Alaska are not becoming indistinguishable from EU licenses by accident.
EU police officers do not want words: note that the Norwegian license I linked above is practically wordless. The idea of the Vienna Convention is to replace nearly all the words on licenses with standard numbers where every number is defined in a certain way, 1 is surname, 3 is date of birth, etc., so there is no need for any language. Considering the EU I think that’s the clever way to go. North America should do the same, and is, except for the bigger state and province holdouts I listed above. Certainly the majority of states and provinces are well on their way to Vienna convention conformance.
The IDP is a 20th century artifact from a pre-standardization era. Its days are numbered. Already about half of European countries don’t require one of North Americans, and another quarter have laws that are never enforced against North Americans, leaving only about 25% iffy where there is a small chance of any use. Wouldn’t it be nice to make all the EU countries the same? Wouldn’t it be nice to not have to pack an extraneous item? Until every state and province is on board there’s no chance of that happening.
So the IDP is not a translation, it's not some courtesy we show to non-English speaking people, it's not a "way to show respect to the local culture," not any of that. The emotion some people place on those pages is kind of overwhelming to me.
I do wish the IDP lasted longer than a single year.
My understanding is that the treaty that established it restricts the age to 1 year, it's not up to AAA to set the time limit.
